Wiggins, MS 39577 Frost Dates
Wiggins, MS: when does the frost end?
Around 03/14 is the usual last spring frost, about 198 days away. Fall's first freeze usually shows up around 11/18, roughly 249 days after the last spring frost.
Zone 8b (15 to 20°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Wiggins, not a forecast for this year.
Stretching the season past the first frost
With roughly 12 weeks until Wiggins's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/14 isn't a guarantee
03/14 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/21 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/02 and only about 1 year in 10 sees frost after that.
